IMPROVEM ENT l N SEEDlNG-MACHINES.

Specification forming part of Letters Patent No. 37.753, dated February 24, 1863.

To all whom it may concern:

Be it known that I, GEORGE D. HAWORTH, of Decatur, in the county of Macon and State of Illinois, have invented a new and Improved Seeding Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, making a part of this specification, in which-.

Figure 1 is a side sectional view of my inventiomtaken in thelineww, Fig.2. Fig.2 is a plan or top view of thesame; Fig. 3, a transverse section of a portion ofthe same, taken in the line 3; Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

The invention consists in the employment or use of scrapers applied to themachine andarranged in such a manner that the wheels on g which themachine is mounted maybe readily cleaned and the scrapers applied to the wheels only when'necessary.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

Arepresents whatmay be termed the main frame of the machine,which is composed of a bar, a, having a cross-bar, I), attached" to its back part at right angles andfirmly secured in position by oblique bars or braces c c.-

. i B is the axle, which is secured to the bar a I and braces 0 c in a'position parallel with the cross-bar b.

O G are wheels-placed on the axle B, and D is the draft-pole,\vhich is attached to the front end of the bar a.

To the front part of the-bar a of the main frame A there is secured at right angles a bar,

,(I, which is'firmly retained in positionby oblique braces 0.0. (See Fig. 2.)

To each end of the bar 01 there is attached by a hinge orjoint,f, a bar, E. These bars E extend back toward the wheels (J0,parallel with each other, and the bar a and the back parts of the bars E are connected by across-bar, F. The bars E E and cross-bar F may be termed a supplemental frame, and it is allowed to swing freely from the cross-bar d of the frame A on account of the joints or hingesf.

On the back part of each barE there is placed a seed-hopper, G. These seed-hoppers have perforated bottoms g, and underneath the bottoms 9 there are placed circularplates H,which have eachtwo small perforations, h h, in them, which are smaller than the perforations-i in the bottoms g of the hoppers, there being also two perforations, i, in each seed-hopper. (SeeFig. 2.) The front ends of the plates H project'beyond the front parts of the seed-hoppers, and they are connected by a bar, I, by operating which with a reci rocating motion the seed is discharged from the hoppers. This arrange men't, however, is not new, it having been previously used in other seeding-machines.

1 The seed is discharged fromthe hoppers G G into tubes J J, which have open backs,

and are provided at theirlower ends with furrow-shares K. In front of each tube J and, share. K there-is arntary colter,-L. These colters are constructed of circular pieces of metal, (steel would be the preferable material,) and their axes j are fitted in bearings M, which are attached to the under sides of the bars E E. (See Fig. 1.) The colters L are allowed to rotate freely and in contact with what I term nose-pieces N,which are simply metal plates secured to the front ends of the shares K K, said nose-pieces projecting slightly below the bottoms of the shares K and exgending forward sufficiently far to been contact with the inner surfaces of the lower parts of the colters, as shown clearly in Fig. 1. By this arrange.

mentit will be seen that as the machine is drawn along all obstructions-such as stalks and the like-.-will be prevented from being caught by the shares, for the nosepieces N completely close up the spaces between the lower parts of the colters and the shares, and enable the latter to pass over all obstructions, whether cut through or divided bythe colters or not. The difiiculty therefore attending the";

gathering of weeds and trash around the tubes or standards of the furrow-shares is by thisinvention fully obviated.

0 represents a sliding or reciprocating bar, which is fitted in guides k 70, attached to the cross-bar b. This bar O has two scrapers. P P, attached to it,which are directly back of the wheels 0 O. The scrapers P P are much narrower than the wheels 0 O, as will be seen by referring toFig. 2, and the movement of the bar '0 is suflicient to admit of the scrapers pass ing over the entire surfaces of the wheels 0.- The bar 0 has an upright handle, Q, attached to it for the convenience of moving it. This handle projects upward within reach of the drivers seat R, which is attached to a frame, S, the front of the latter being secured by a joint, I, to uprights mou the cross-bar Fof the supplemental frame to which the seed-hoppers are attached. This frame S is snpportedvby a hinged bar, T, by adjusting which the shares and colters may, whennecessary, be elevated above the surface of the ground. Thedroppers seat U is attached to the lower part of the frame S. By this arrangement of the sliding bar 0, with narrow scrapers P attached, it will be seen that the surfaces or treads of the wheels 0 C may be cleaned at any time by simply moving the bar 0 soithat thescrapers will pass over the surfaces or treads of the wheels, and when the scrapers are not in use they are not in contact with the wheels, the rod 0 being so adjusted that the scrapers will be at one side of them.

Having thus described my invention, what I
